CVSS: 7.5EPSS: 72%CPEs: 23EXPL: 0CVE-2019-0199 – tomcat: Apache Tomcat HTTP/2 DoS
https://notcve.org/view.php?id=CVE-2019-0199
The HTTP/2 implementation in Apache Tomcat 9.0.0.M1 to 9.0.14 and 8.5.0 to 8.5.37 accepted streams with excessive numbers of SETTINGS frames and also permitted clients to keep streams open without reading/writing request/response data. By keeping streams open for requests that utilised the Servlet API's blocking I/O, clients were able to cause server-side threads to block eventually leading to thread exhaustion and a DoS. La implementación HTTP/2 en Apache Tomcat desde 9.0.0.M1 hasta 9.0.14 y desde 8.5.0 hasta 8.5.37 aceptaba flujos con números excesivos de tramas SETTINS y permitía a los clientes mantener flujos abiertos sin datos de lectura/escritura o solicitud/respuesta. Manteniendo flujos abiertos para peticiones que utilizaban bloqueo I/O en el Servlet API´s, los clientes eran capaces de hacer que los hilos (threads) del lado del servidor se bloquearan, provocando el agotamiento de los hilos y la denegación del servicio (DoS). A flaw was found in Apache Tomcat, where the HTTP/2 implementation accepted streams with excessive numbers of SETTINGS frames and also permitted clients to keep streams open, which enables them to cause server-side threads to block. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00090.html http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00013.html http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00054.html http://www.securityfocus.com/bid/107674 https://access.redhat.com/errata/RHSA-2019:3929 https://access.redhat.com/errata/RHSA-2019:3931 https://lists.apache.org/thread.html/158ab719cf60448ddbb074798f09152fdb572fc8f781e70a56118d1a%40%3Cdev.tomcat.apache.org%3E https://lists.apache.org/thre • CWE-400: Uncontrolled Resource Consumption •
CVSS: 5.3EPSS: 78%CPEs: 53EXPL: 2CVE-2018-11784 – Apache Tomcat 9.0.0.M1 - Open Redirect
https://notcve.org/view.php?id=CVE-2018-11784
When the default servlet in Apache Tomcat versions 9.0.0.M1 to 9.0.11, 8.5.0 to 8.5.33 and 7.0.23 to 7.0.90 returned a redirect to a directory (e.g. redirecting to '/foo/' when the user requested '/foo') a specially crafted URL could be used to cause the redirect to be generated to any URI of the attackers choice. Cuando el servlet por defecto en Apache Tomcat en versiones de la 9.0.0.M1 a la 9.0.11, de la 8.5.0 a la 8.5.33 y de la 7.0.23 a la 7.0.90 devolvía una redirección a un directorio (por ejemplo, redirigiendo a "/foo/'' cuando el usuario solicitó '"/foo") se pudo usar una URL especialmente manipulada para hacer que la redirección se generara a cualquier URI de la elección del atacante. These are details on an open redirection vulnerability in Apache Tomcat version 9.0.0M1 that was discovered in 2018. • https://www.exploit-db.com/exploits/50118 https://github.com/Cappricio-Securities/CVE-2018-11784 http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00030.html http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00056.html http://packetstormsecurity.com/files/163456/Apache-Tomcat-9.0.0M1-Open-Redirect.html http://www.securityfocus.com/bid/105524 https://access.redhat.com/errata/RHSA-2019:0130 https://access.redhat.com/errata/RHSA-2019:0131 https://access.redhat.c • CWE-99: Improper Control of Resource Identifiers ('Resource Injection') CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
CVSS: 9.1EPSS: 0%CPEs: 23EXPL: 0CVE-2018-8037 – tomcat: Due to a mishandling of close in NIO/NIO2 connectors user sessions can get mixed up
https://notcve.org/view.php?id=CVE-2018-8037
If an async request was completed by the application at the same time as the container triggered the async timeout, a race condition existed that could result in a user seeing a response intended for a different user. An additional issue was present in the NIO and NIO2 connectors that did not correctly track the closure of the connection when an async request was completed by the application and timed out by the container at the same time. This could also result in a user seeing a response intended for another user. Versions Affected: Apache Tomcat 9.0.0.M9 to 9.0.9 and 8.5.5 to 8.5.31. Si la aplicación completaba una petición async al mismo tiempo que el contenedor activaba el tiempo de espera de async, existía una condición de carrera que podía hacer que un usuario viera una respuesta destinada a otro usuario. • http://mail-archives.us.apache.org/mod_mbox/www-announce/201807.mbox/%3C20180722090623.GA92700%40minotaur.apache.org%3E http://mail-archives.us.apache.org/mod_mbox/www-announce/201808.mbox/%3C0c616b4d-4e81-e7f8-b81d-1bb4c575aa33%40apache.org%3E http://www.oracle.com/technetwork/security-advisory/cpuoct2018-4428296.html http://www.securityfocus.com/bid/104894 http://www.securitytracker.com/id/1041376 https://access.redhat.com/errata/RHSA-2018:2867 https://access.redhat.com/errata/RHSA-2018:2868 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
